ABSTRACT
I will survey recent developments in the use of group-invariant histograms, using distances,
areas, etc., and signatures, using differential invariants, joint invariants, invariant numerical
approximations, etc., for object recognition and symmetry detection in images, including
recent applications to automated jigsaw puzzle assembly.
